What is a job?

A job is what runs your build process on CircleCI 2.0. Jobs are defined in your CircleCI 2.0 config.yml. A simple config.yml [needs at least one job](https://circleci.com/docs/2.0/jobs-steps/) in order to run a build. Using workflows, you can define multiple jobs that run in a specific sequence, in parallel, and various other nifty configurations.
